Another foul ball from New York Times columnist Paul Krugman. Mr. “Often Wrong but Never in Doubt” writes:

Just think about this for a minute. It’s one thing when politicians refuse to spend money helping the poor and vulnerable; that’s just business as usual. But here we have a case in which politicians are, in effect, spending large sums, in the form of rejected aid, not to help the poor but to hurt them.

And as I said, it doesn’t even make sense as cynical politics. If Obamacare works (which it will), millions of middle-income voters — the kind of people who might support either party in future elections — will see major benefits, even in rejectionist states. So rejectionism won’t discredit health reform. What it might do, however, is drive home to lower-income voters — many of them nonwhite — just how little the G.O.P. cares about their well-being, and reinforce the already strong Democratic advantage among Latinos, in particular.

Rationally, in other words, Republicans should accept defeat on health care, at least for now, and move on. Instead, however, their spitefulness appears to override all other considerations. And millions of Americans will pay the price.
